Slightly too close to the canopy with my tops(13”) but most mid canopy is getting 800/1100 umols. I am also running a Phillips 600w hps so 1200w total in a 9x5. Everything seems optimal so we’ll just wait, only slight thing is ec has started to go up since week 5 so I’ve been topping up with phd tap water to counter until fresh weekly change
Wow, just checked original thread post for strain info. I remember this post when it first came up, nice transition!
My run with photo indica heavy strain took a while just to show preflowers, let alone that much frost like yours.
Wild guess, it is indica heavy photo? Either way it has lots of room to yield, you have plenty of plants. I go by ppfd, not sure what that hps would be equivelent to, only did hps one time.
I think I last had brought to my attention to not use too much ppfd or exceed DLI. I lst and scrog for height and extra colas for more yield but you can still get 30oz easy from glancing through complete grow journals in hydro.
I think 8oz per 4 sqr foot is about the limit or 10-12 every 2.5x2.5 of space. Anything more takes extra talent.
